A 52-year-old woman with malignant serous cystic neoplasm of the pancreas and metachronous hepatic metastasis. a Contrast-enhanced CT scan demonstrates a 9 × 8 cm solid and cystic mass in the pancreatic head. b FDG-PET/CT scan demonstrates no increased uptake within the tumor. c Photograph of the gross specimen shows a well-demarcated lobulated mass. The cut surface showed a yellowish, gray, firm tumor with multiple microcystic changes and fibrous septa. d Photomicrograph shows multiple microcysts lined by a single layer of cuboidal epithelium with a clear cytoplasm (H and E stain, ×200). e Contrast-enhanced CT scan shows a low-attenuating nodular lesion with peripheral rim enhancement in liver segment VII. f On T2-weighted MR image, the liver tumor shows very bright signal intensity like cerebrospinal fluid. g On contrast-enhanced T1-weighted MR image during the portal-venous phase, the tumor shows peripheral rim enhancement. h Photomicrograph shows that the tumor is composed of multiple microcysts separated by collagen fibers, which are lined by a single layer of cuboidal epithelium with a clear cytoplasm and bland-looking nuclei (H and E stain, ×200)
